TREE-PRUNER.-

Specification of Letters Patent.

. Patented Mar. "2, 1916.

Application fi led September 24, 1914. Serial No. 863,344.

To all whom it may concern --Be it known that 1, DAVID H. 'WATTs, acitizen of the United States of America, residing at Kerrmoor, inthecounty of Clearfield and State of Pennsylvania. have invented certainnew and useful Improvements in Tree-Pruners, of which the following is aspecification, reference being hadof a tree.

Another object of this invention is the production of a tree prunerhaving a reciprocal head mounted upon a stationary rod, this head beingso formed as to normally remain in engagement with the end of he rod butwhich may be easily detached from the rod when desired whereby thedirect blows upon the rod may cause the same to sever a twig or a limbwithout danger of the several portions becoming accidentally disengaged.

With these and other objects in view this invention consists of certainnovel combinations, constructions, and arrangements of parts as will behereinafter fully described and claimed.

Referring to the accompanying drawing: Figure 1 is a detailedperspective view of the assembled tree .pruner illustrating the mannerin which the head thereof is reciprocated. Fig. 2 is a side elevationofthe stationary rod and blade showing the reciprocal head in section.Fig. 8 is an enlarged longitudinal section taken through the reciprocalhead showing the manner in which the end of the stationary rod isengaged. Fig. 4 is a section taken on the line 4. 4. of Fig. 3 lookingin the direction of the arrow. Fig. 5 is a fragmentary detailedperspective view of the inner end of the stationary rod showing theferrule detachablycarried thereby. I v

Referring to the accompanying drawing by numerals 1 designates thehollow tubing having the enlarged central bore 2 extendingtlierethrough. The threaded end 3 of the tubing 1 carries the cap 4:having a reduced end 5. This reduced end 5 has a reduced opening 6formed therein through which the stationaryv rod 7 passes. This rod 7 isprovided. at its inner end with a ferrule 8 which is held in position bymeans of the screw 9. This ferrule 8 is positioned within the bore 2 ofthe hollow tubing 1 so 1 art.

as to allow the tubing to easily reciprocate thereon since the bore 2 isof suflicient size to accommodate the ferrule 8. Since the cap 4: isprovided with a pocket 10 of the same size as the diameter of theferrule 8, the ferrule may pass thereinto but the movement of the headin onedirection upon the rod 7 will be limited. The opposite end of thetubing lis provided with a threaded portion 11 upon which thedouble-ended collar 12is detachably carried.- The end 13 of the collar12 engages the threaded end 11 of' the tubing 1 while the opposite end14 of the collar receives the reduced threaded neck 15 of the woodenhandle 16. By the use of this wooden handle 16 it will be seen that thetree pruner may be easily held so as to cause the reciprocal head toimpart a direct blow with a considerable force upon the inner end of therod 7 without injury to the persons hands who is using the device. Inorder to deaden the impact caused when the reciprocal head imparts ablow to the inner end of the rod 7 there is provided a comparativelythin washer 17 which is formed of leather or other suitable materialwhich bears upon the central body 18 of the doubleended collar 12. Thiswasher is for the purpose of deadening the impact caused when thereciprocal head directs or imparts a blow to the inner end of the rod 7thereby preventing inJury' to the several portions of the device.

A blade 19 having a beveled outer end 20 is mounted upon the rod 7 andis adapted to When this device is in use the blade or will sever smalland large twigs or limbs alike. It is of course obvious that the rod 7may be removed from the tubing when so desired for the substitution of adilferent rod having a different size chisel or blade.

From the foregoing description it will be seen that a simple andefiicient tree pruner has been produced which is so formed as to engagea single twig or limb for eliiciently and quickly severing the samewithout injury to the adjacent limbs and also which is provided with asimple and eflicient reciprocal head which is adapted to impart theblows to the end of the rod.

What I claim is 2- In a tree pruner of the class described, thecombination of a stock comprising a hollow tubing, a rod slidablymounted within said tubing and provided with a ferrule upon its innerend, a cap carried upon one end of said tubing for limiting the slidingmovement of rod in one direction, a double-ended collar threaded uponthe outer portions of the opposite end of said tubing, said collarprovided with a central body, a bufier washer carried within said collarand resting upon said body, the inner end of said tubing bearing uponsaid washer adjacent its outer periphery, whereby said washer will bepositively retained in its correct position, saidv washer being adaptedto form a buffer for the inner end of said rod and ferrule for absorbingthe jar when the rodv Copies of this patent may be obtained for fivecents each, by addressing the Commissioner of Patents, WashingtomD.
